: Hi, another thing I forgot, but important in this issue:
allready made a wooden kajak ( glassfiber and epoxy)

Last summer we made a week in Poland ( 5 days camping and trekking)
Unluckily we had many portages over fallen trees and I saw the damage ( I can fix it well)but I would use the canoe in semi white water , rocks and so on.

At this moment I was just curious if I could build a canoe totally whitout glass and epoxy !

Or beneath the waterline in plastic ( a little flex tolerated) and the upper part
wood ......or
Maybe beneath the waterline kind of canvas (pvc maybe a la Tom Yost) but it tears rather easily in sharp surrounding.......or
Build in wooden strips and beneath the waterline thinner strips with plastics
strokes glued on .......or
Just strip building complete and beneath strokes of plasic (rubber) every 10 cm

You see: still fooling around with some ideas .. and still curious at others!

Anyway , apologize for my bad english ( I' m from Flanders (Belgium) )

Everybody , thank you allready for your input
